Ahh...Well thanks for the offer to look for it for me, but I think I can find them...This is my first built PC. Thing is, I nuked my hp laptop and dear god...finding drivers for hp products is like finding a needle in a haystack. I'm just a bit worried I'll have that experience again, but I'm sure I'll find it, thanks! Here is what I got, but don't worry

I usually use the disks to install the basic drivers just to get the PC running, then I first get the latest graphics drivers from AMD or Nvidia.
From there I run windows update to check what it can find. Then as time goes by I will check for new drivers for each component(Lan drivers, sound, latest BIOS, USB3, etc). It just takes to long to do it all at once. But graphics drivers are VERY important so I keep those as updated as possible.
Chip set drivers for the motherboard would be the most critical first driver to install to ensure best possible outcome to allow the operating system know what the motherboard is capable of.
Usually drivers off the original cd are good enough, i wouldn't worry too much unless there are major issues recorded, otherwise no harm in downloading an updated version just for the sake of it.
2nd driver to install can be anything, from lan, sound, video to other addons - it is recommended installing latest versions but i wouldn't concern yourself using original drivers (except for video drivers) if you're not experiencing any problems.
People have all kinds of ways and priorities, this is mine, as long as the chip set driver is installed first and directx along with the video driver all should be working properly
After that its more or less trial and error and getting to know your rig before making any further tweaks based on reliability and performance should you look for bios fixes.
Notebooks where the operating system and drivers are put on a separate partition will probably (like you) have a hard time finding drivers for everything if the entire hdd is wiped or it is changed out.
Notebook vendors usually recommend to create first time os restore\backup in case this happens because its rare for them to provide physical discs included with a preloaded operating system package.
Eventually things can be done, but the easiest way to restore is to f8 or 10 during boot to reconfigure for factory default reinstalling the original os image.
